如何：将数据直接发送到 XPS 打印机

  • 项目

本主题介绍如何将打印机控制数据直接发送到使用 XPSDrv 打印机驱动程序的打印机。

以下步骤介绍如何将数据直接发送到打印机。 后面的代码示例中也演示了这些步骤。

  1. 调用 OpenPrinter 以获取打印机的句柄。
  2. 使用打印机数据初始化 DOCINFO 结构。
  3. 调用 StartDocPrinter 以指示应用程序将向打印机发送文档数据。
  4. 调用 WritePrinter 以发送数据。
  5. 调用 EndDocPrinter 以指示已发送此文档的所有数据。
  6. 调用 ClosePrinter 以释放资源。

将打印机控制数据直接发送到使用 XPSDrv 打印机驱动程序的打印机。

// 
//  RawDataToXpsPrinter - sends binary data directly to a printer 
//          with an XPSDrv Printer Driver 
//  
// szPrinterName: NULL-terminated string specifying printer name 
// lpData:        Pointer to raw data bytes 
// dwCount        Length of lpData in bytes 
//  
// Returns: TRUE for success, FALSE for failure. 
//

        // Enter the datatype of this buffer.
        //  Use "XPS_PASS" when the data buffer should bypass the 
        //    print filter pipeline of the XPSDrv printer driver. 
        //    This datatype would be used to send the buffer directly 
        //    to the printer, such as when sending print head alignment 
        //    commands. Normally, a data buffer would be sent as the
        //    "RAW" datatype.
